Information
RHEL 9 must not have a Trivial File Transfer Protocol (TFTP) server package installed.
GROUP ID: V-257835
RULE ID: SV-257835r1069368
Removing the "tftp-server" package decreases the risk of the accidental (or intentional) activation of tftp services.
If TFTP is required for operational support (such as transmission of router configurations), its use must be documented with the information systems security manager (ISSM), restricted to only authorized personnel, and have access control rules established.
Solution
The "tftp-server" package can be removed with the following command:
$ sudo dnf remove tftp-server
